Abstract: A three-dimensional modeling apparatus includes an ejection portion capable of ejecting a fluid material, which is a material of an object, and a control portion that forms a laminated body in which one layer or more of cross-section bodies are laminated by executing one or more repetitions of a cross-section body formation process, which forms a cross-section body equivalent to one layer of the object by controlling the ejection portion and ejecting the fluid material. The control portion executes a correction process that ejects the fluid material onto a target correction location, which is at least a portion of an outline section of an upper surface of the laminated body.

Abstract: A three-dimensional modeling apparatus includes an ejection portion capable of ejecting a fluid material, and a control portion that forms a laminated body in which one layer or more of cross-section bodies are laminated by executing one or more repetitions of a cross-section body formation process. The control portion reduces a total amount of the fluid material to be ejected at a first coordinate, which configures the apex that corresponds to the recess, to be lower than a total amount of the fluid material to be ejected at a second coordinate, which configures a region other than an outline section of the planar shape in a case in which an apex, which corresponds to a recess in a planar shape when the laminated body is viewed from above in a planar manner, is present.
